I'm running a Windows 10, I-7 machine with a 27" Asus monitor. The monitor has multiple USB connections. My Canon's, 7dII & 5d3 have different plugs so I had one cord in the computer & one in the monitor so I didn't have to swap cords every time I downloaded.
The computer lost its mind & doesn't see the monitors ports any more. Where do I tell the computer to recognize the monitors USB ports?

Right click on the windoze icon in the lower left of your screen. Left click on Device Manager.

I would re-install the monitor drivers and the USB drivers. Instructions are here:

https://support.microsoft.com/en-us/windows/update-drivers-in-windows-ec62f46c-ff14-c91d-eead-d7126dc1f7b6

You can do both removals at once and then reboot. Make sure you DO NOT check the box to "Delete the drivers software for this device".

First, make sure the USB cable between the monitor and the PC is still connected properly.

Agree here with stars.

Monitors/ can have a wide variety of ports which serve different purposes. I bought two identical computers set one up fine. Second one, no response on monitor, very quiet systems, so I sent 2nd back for replacement. Before it arrived I discovered my error, cable in wrong port, emailed company, I was correct about it all, lucky for me they were very understanding.

Me & my wife have the same monitors. Mine works as a USB hub, hers does not. I'm not sure why. Since she does little in the way of advanced use of a PC, it isn't important.

Did you check using the exact same cables and devices, I mean try yours on hers. I ran into very troublesome issues with a telescope and different high quality cables a while back. Everything fine, then intermittent power issues. Eventually used to power packs to be sure sufficient power, not a good answer, but solved problem for last four months and better than shipping system back to Europe only to be told it was a power issue due to cabling or suck.
Just a thought.

Also, some times, identical things aren't really, small change not mentioned. Had a Ford Torino that had to take parts to store to be sure one got the correct thing, knowing year, model, etc. was useless (This from the parts store, not my stupidity.

Go to settings and run Troubleshoot. Good luck.

Of course most everything else is different, different PC, different Op system, different video chip. As I implied previously, she doesn't need the extra USB ports.

You can go into Device Manager and look for us ports it any are highlighted in yellow then click on them and you open up a file similar to checking your hard drive go in to that file and reinstall the usb drivers

I went into device manager thinking it would show the available USB ports. Nope. Stuck a flash drive into one of the ports & Mr.Computer found it. So I plugged both down load cables into the monitor, turned the camera(s) on, DPP fired up & successfully downloaded my pics. I'm convinced that computers are subject to Alzheimers on occasion.

There are also, or at least were, little known things that caused problems. For an earlier windows, there was an event counter. Each time you opened a file, etc. it counted up. At same va!ue, computer stopped I believe. I quess idea was to be sure computer was restarted periodically to avoid accumulated dust bunnies? At any rate, this counter occupied a tiny, set amount of memory which could be easily expanded with no performance loss. Something told in one of those tibbits section of PC magazine I believe.

They say it is impossible to ever prove code is perfect and with so many programs, peripherals with their own processors and memory who knows what rare! interactions can occur. There are often things you can do in coding, but should not do according to specifications. The best non-computer example I know is a true occuence: Never store things on hot plates not in storage! At work, there was a large hot plate in a hood that was never used, but was connectable. Everyone stored things on it as it was never used, except by a visiting scientist one day. Took hours for the box of storage bottles to ignite in middle of night. Hood contained fire, but lab was black with soot everywhere.
